We have obtained Delta(f)H(298) for 11 C-5 cyclic hydrocarbons by calc
ulating Delta(hyd)H(298) and Delta(isom)H(298) via the G2(MP2) and G2(
MP2,SVP) ab initio methods, taking Delta(f)H(298)(cyclopentene) as a k
nown reference point. The arithmetic mean deviation between G2(MP2) ca
lculated Delta(f)H(298) and experimental Delta(f)H(298) values is < 1
kcal mol(-1) for the 5 compounds that have been studied experimentally
